ENZYMES

Activation energy

Types of co-factors

Inorganic co-factors are detachable.

Reversible noncompetitive

Irreversible Non competitive

Summary

Competitive Non-competitive

Inhibits the enzyme activity Inhibits the enzyme activity

Increasing the inhibitorconcentration increases the effect

Changing the concentration of inhibitor does not influence the effect

Inhibitor competes with the substrate at the active site (similar molecule)

Inhibitor does not bind at the active site

Active site stays the same Active site may change shape(e.g. allosteric inhibition)
